BACKGROUND OF THE INVENTION

1. Field of the Invention

The present disclosure relates to an optical image capturing system, and more particularly to a compact optical image capturing system which can be applied to electronic products.

2. Description of the Related Art

In recent years, with the rise of portable electronic devices having camera functionalities, the demand for an optical image capturing system is raised gradually. The image sensing device of ordinary photographing camera is commonly selected from charge coupled device (CCD) or complementary metal-oxide semiconductor sensor (CMOS Sensor). In addition, as advanced semiconductor manufacturing technology enables the minimization of pixel size of the image sensing device, the development of the optical image capturing system directs towards the field of high pixels. Therefore, the requirement for high imaging quality is rapidly raised.

The traditional optical image capturing system of a portable electronic device comes with different designs, including a four-lens or a five-lens design. However, the requirement for the higher pixels and the requirement for a large aperture of an end user, like functionalities of micro filming and night view, or the requirement of wide view angle of the portable electronic device have been raised. But the optical image capturing system with the large aperture design often produces more aberration resulting in the deterioration of quality in peripherical image formation and difficulties of manufacturing, and the optical image capturing system with wide view angle design increases distortion rate in image formation, thus the optical image capturing system in prior arts cannot meet the requirement of the higher order camera lens module.

Therefore, how to effectively increase quantity of incoming light and view angle of the optical lenses, not only further improves total pixels and imaging quality for the image formation, but also considers the equity design of the miniaturized optical lenses, becomes a quite important issue.

SUMMARY OF THE INVENTION

The vertical coordinate axis of the characteristic diagram of modulation transfer function represents a contrast transfer rate (values are from 0 to 1). The horizontal coordinate axis represents a spatial frequency (cycles/mm; lp/mm; line pairs per mm). Theoretically, an ideal image capturing system can 100% show the line contrast of a photographed object. However, the values of the contrast transfer rate at the vertical coordinate axis are smaller than 1 in the actual image capturing system. The transfer rate of its comparison value is less than a vertical axis. In addition, comparing to the central region, it is generally more difficult to achieve a fine degree of recovery in the edge region of image capturing. The contrast transfer rates (MTF values) with spatial frequencies of 55 cycles/m at the optical axis, 0.3 field of view and 0.7 field of view of a visible spectrum on the image plane are respectively denoted by MTFE0, MTFE3 and MTFE7. The contrast transfer rates (MTF values) with spatial frequencies of 110 cycles/m at the optical axis, 0.3 field of view and 0.7 field of view on the image plane are respectively denoted by MTFQ0, MTFQ3 and MTFQ7. The contrast transfer rates (MTF values) with spatial frequencies of 220 cycles/m at the optical axis, 0.3 field of view and 0.7 field of view on the image plane are respectively denoted by MTFH0, MTFH3 and MTFH7. The contrast transfer rates (MTF values) with spatial frequencies of 440 cycles/m at the optical axis, 0.3 field of view and 0.7 field of view on the image plane are respectively denoted by MTF0, MTF3 and MTF7. The three fields of view described above are representative to the centre, the internal field of view and the external field of view of the lens elements. Thus, they may be used to evaluate whether the performance of a specific optical image capturing system is excellent. The design of the optical image capturing system of the present invention mainly corresponds to a pixel size in which a sensing device below 1.12 micrometers is includes. Therefore, the quarter spatial frequencies, the half spatial frequencies (half frequencies) and the full spatial frequencies (full frequencies) of the characteristic diagram of modulation transfer function respectively are at least 110 cycles/mm, 220 cycles/mm and 440 cycles/mm.

If an optical image capturing system needs to satisfy with the images aimed to infrared spectrum, such as the requirement for night vision with lower light source, the used wavelength may be 850 nm or 800 nm. As the main function is to recognize shape of an object formed in monochrome and shade, the high resolution is unnecessary, and thus, a spatial frequency, which is less than 100 cycles/mm, is used to evaluate the functionality of the optical image capturing system, when the optical image capturing system is applied to the infrared spectrum. When the foregoing wavelength 850 nm is applied to focus on the image plane, the contrast transfer rates (MTF values) with a spatial frequency of 55 cycles/mm at the optical axis, 0.3 field of view and 0.7 field of view on the image plane are respectively denoted by MTFI0, MTFI3 and MTFI7. However, the infrared wavelength of 850 nm or 800 nm may be hugely different to wavelength of the regular visible light wavelength, and thus, it is hard to design an optical image capturing system which has to focus on the visible light and the infrared light (dual-mode) simultaneously while achieve a certain function respectively.

The disclosure provides an optical image capturing system, which is able to focus on the visible light and the infrared light (dual-mode) simultaneously while achieve a certain function respectively, and an object-side surface or an image-side surface of the fourth lens element has inflection points, such that the angle of incidence from each field of view to the fourth lens element can be adjusted effectively and the optical distortion and the TV distortion can be corrected as well.

A horizontal distance in parallel with the optical axis from a coordinate point on the object-side surface of the first lens element at height ½ HEP to a coordinate point on the image-side surface of the sixth lens element at height ½ HEP is EIN. The following relations are satisfied: 1.2≦f/HEP≦10.0, HOI>3.0 mm and 0.2≦EIN/ETL<1.

The disclosure provides another optical image capturing system, in order from an object side to an image side, including a first, second, third, fourth, fifth, sixth lens elements and an image plane. Wherein the optical image capturing system consists of six lens elements with refractive power, a maximum height for image formation on the image plane perpendicular to the optical axis in the optical image capturing system is denoted by HOI, and at least two lens elements among the first through the sixth lens elements are made of glass material.

The following relations are satisfied: 1.2≦f/HEP≦3.0, 0.4≦| tan(HAF)|≦6.0, HOI>3.0 mm and 0.2≦EIN/ETL<1.

A thickness of a single lens element at height of ½ entrance pupil diameter (HEP) particularly affects the corrected aberration of common area of each field of view of light and the capability of correcting optical path difference between each field of view of light in the scope of ½ entrance pupil diameter (HEP). The capability of aberration correction is enhanced if the thickness becomes greater, but the difficulty for manufacturing is also increased at the same time. Therefore, it is necessary to control the thickness of a single lens element at height of ½ entrance pupil diameter (HEP), in particular to control the ratio relation (ETP/TP) of the thickness (ETP) of the lens element at height of ½ entrance pupil diameter (HEP) to the thickness (TP) of the lens element to which the surface belongs on the optical axis. For example, the thickness of the first lens element at height of ½ entrance pupil diameter (HEP) is denoted by ETP1. The thickness of the second lens element at height of ½ entrance pupil diameter (HEP) is denoted by ETP2. The thicknesses of other lens elements are denoted in the similar way. A sum of ETP1 to ETP6 described above is SETP. The embodiments of the present invention may satisfy the following relation: 0.3≦SETP/EIN<1.

In order to enhance the capability of aberration correction and reduce the difficulty for manufacturing at the same time, it is particularly necessary to control the ratio relation (ETP/TP) of the thickness (ETP) of the lens element at height of ½ entrance pupil diameter (HEP) to the thickness (TP) of the lens element on the optical axis lens. For example, the thickness of the first lens element at height of ½ entrance pupil diameter (HEP) is denoted by ETP1. The thickness of the first lens element on the optical axis is TP1. The ratio between both of them is ETP1/TP1. The thickness of the second lens element at height of ½ entrance pupil diameter (HEP) is denoted by ETP2. The thickness of the second lens element on the optical axis is TP2. The ratio between both of them is ETP2/TP2. The ratio relations of the thicknesses of other lens element in the optical image capturing system at height of ½ entrance pupil diameter (HEP) to the thicknesses (TP) of the lens elements on the optical axis lens are denoted in the similar way. The embodiments of the present invention may satisfy the following relation: 0.2≦ETP/TP≦3.

A horizontal distance between two adjacent lens elements at height of ½ entrance pupil diameter (HEP) is denoted by ED. The horizontal distance (ED) described above is in parallel with the optical axis of the optical image capturing system and particularly affects the corrected aberration of common area of each field of view of light and the capability of correcting optical path difference between each field of view of light at the position of ½ entrance pupil diameter (HEP). The capability of aberration correction may be enhanced if the horizontal distance becomes greater, but the difficulty for manufacturing is also increased and the degree of ‘miniaturization’ to the length of the optical image capturing system is restricted. Thus, it is essential to control the horizontal distance (ED) between two specific adjacent lens elements at height of ½ entrance pupil diameter (HEP).

In order to enhance the capability of aberration correction and reduce the difficulty for ‘miniaturization’ to the length of the optical image capturing system at the same time, it is particularly necessary to control the ratio relation (ED/IN) of the horizontal distance (ED) between the two adjacent lens elements at height of ½ entrance pupil diameter (HEP) to the horizontal distance (IN) between the two adjacent lens elements on the optical axis. For example, the horizontal distance between the first lens element and the second lens element at height of ½ entrance pupil diameter (HEP) is denoted by ED12. The horizontal distance between the first lens element and the second lens element on the optical axis is IN12. The ratio between both of them is ED12/IN12. The horizontal distance between the second lens element and the third lens element at height of ½ entrance pupil diameter (HEP) is denoted by ED23. The horizontal distance between the second lens element and the third lens element on the optical axis is IN23. The ratio between both of them is ED23/IN23. The ratio relations of the horizontal distances between other two adjacent lens elements in the optical image capturing system at height of ½ entrance pupil diameter (HEP) to the horizontal distances between the two adjacent lens elements on the optical axis are denoted in the similar way.

A horizontal distance in parallel with the optical axis from a coordinate point on the image-side surface of the sixth lens element at height ½ HEP to the image plane is EBL. A horizontal distance in parallel with the optical axis from an axial point on the image-side surface of the sixth lens element to the image plane is BL. The embodiments of the present invention enhance the capability of aberration correction and reserve space for accommodating other optical elements. The following relation may be satisfied: 0.2≦EBL/BL<1.1. The optical image capturing system may further include a light filtration element. The light filtration element is located between the sixth lens element and the image plane. A distance in parallel with the optical axis from a coordinate point on the image-side surface of the sixth lens element at height ½ HEP to the light filtration element is EIR. A distance in parallel with the optical axis from an axial point on the image-side surface of the sixth lens element to the light filtration element is PIR. The embodiments of the present invention may satisfy the following relation: 0.1≦EIR/PIR≦1.1.

The height of optical system (HOS) may be reduced to achieve the minimization of the optical image capturing system when the absolute value of f1 is larger than f6 (|f1|>f6).

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| are satisfied with above relations, at least one of the second through fifth lens elements may have weak positive refractive power or weak negative refractive power. The weak refractive power indicates that an absolute value of the focal length of a specific lens element is greater than 10. When at least one of the second through fifth lens elements has the weak positive refractive power, the positive refractive power of the first lens element can be shared, such that the unnecessary aberration will not appear too early. On the contrary, when at least one of the second through fifth lens elements has the weak negative refractive power, the aberration of the optical image capturing system can be corrected and fine tuned.

The sixth lens element may have negative refractive power and a concave image-side surface. Hereby, the back focal length is reduced for keeping the miniaturization, to miniaturize the lens element effectively. In addition, at least one of the object-side surface and the image-side surface of the sixth lens element may have at least one inflection point, such that the angle of incident with incoming light from an off-axis field of view can be suppressed effectively and the aberration in the off-axis field of view can be corrected further.

FIG. 2A is a schematic view of the optical image capturing system according to the second embodiment of the present application, FIG. 2B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the second embodiment of the present application, FIG. 2C is a characteristic diagram of modulation transfer of a visible light according to the second embodiment of the present application, and FIG. 2D is a characteristic diagram of modulation transfer of infrared rays according to the second embodiment of the present application. As shown in FIG. 2A, in order from an object side to an image side, the optical image capturing system includes a first lens element 210, a second lens element 220, a third lens element 230, an aperture stop 200, a fourth lens element 240, a fifth lens element 250, a sixth lens element 260, an IR-bandstop filter 280, an image plane 290, and an image sensing device 292.

The first lens element 210 has negative refractive power and it is made of glass material. The first lens element 210 has a convex object-side surface 212 and a concave image-side surface 214, and both of the object-side surface 212 and the image-side surface 214 are aspheric.

The second lens element 220 has negative refractive power and it is made of plastic material. The second lens element 220 has a concave object-side surface 222 and a concave image-side surface 224, and both of the object-side surface 222 and the image-side surface 224 are aspheric.

The third lens element 230 has positive refractive power and it is made of glass material. The third lens element 230 has a convex object-side surface 232 and a convex image-side surface 234, and both of the object-side surface 232 and the image-side surface 234 are aspheric.

The fourth lens element 240 has positive refractive power and it is made of plastic material. The fourth lens element 240 has a convex object-side surface 242 and a convex image-side surface 244, and both of the object-side surface 242 and the image-side surface 244 are aspheric. The image-side surface 244 has an inflection point.

The fifth lens element 250 has negative refractive power and it is made of plastic material. The fifth lens element 250 has a concave object-side surface 252 and a concave image-side surface 254, and both of the object-side surface 252 and the image-side surface 254 are aspheric. The object-side surface 252 has an inflection point.

The sixth lens element 260 has positive refractive power and it is made of plastic material. The sixth lens element 260 has a convex object-side surface 262 and a concave image-side surface 264. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.

The IR-bandstop filter 280 is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 260 and the image plane 290.

In the optical image capturing system of the second embodiment, a sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relations are satisfied: ΣPP=31.109 mm and f4/ΣPP=0.250. Hereby, it is favorable for allocating the positive refractive power of a single lens element to other positive lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed.

In the optical image capturing system of the second embodiment, a sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relation is satisfied: ΣNP=−32.294 mm and f1/ΣNP=0.456. Hereby, it is favorable for allocating the negative refractive power of a single lens element to other negative lens elements.

The IR-bandstop filter 480 is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 460 and the image plane 490.

In the optical image capturing system of the fourth embodiment, a sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relation is satisfied: ΣPP=13.152 mm and f3/ΣPP=0.469. Hereby, it is favorable for allocating the positive refractive power of a single lens element to other positive lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed.

In the optical image capturing system of the fourth embodiment, a sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relation is satisfied: ΣNP=−89.341 mm and f1/ΣNP=0.125. Hereby, it is favorable for allocating the negative refractive power of a single lens element to other negative lens elements.
